Objective To explore the efficacy of semaglutide in the treatment of type 2 diabetes mellitus(T2DM)com-bined with non-alcoholic fatty liver disease(NAFLD)and its effect on oxidative stress and inflammatory factors.Methods Totally 80 patients with T2DM accompanied by NAFLD admitted to the First Affiliated Hospital of Xinxiang Medical University from July 2021 to December 2022 were selected and randomly assigned to the observation group and the control group,with 40 patients in each group.Patients in the control group were treated with pioglitazone metformin and dapagliflozin,while patients in the observation group were treated with pioglitazone metformin,dapagliflozin,and semaglutide.The levels of glycated hemoglobin(HbA1c),fasting blood glucose(FBG),2-hour postprandial blood glucose(2hPG),body mass,body mass index(BMI),waist circumference,alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyl transferase(GGT),controlled attenuation parameter(CAP),liver stiffness measurement(LSM),malondialdehyde(MDA),glutathione peroxidase(GSH-PX),lipid peroxide(LPO),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-10(IL-10)before and after the treatment were compared.Results After 24 weeks of treatment,the overall response rate(ORR)in the observation group and control group was 92.5％(37/40)and 72.5％(29/40),respectively;and the ORR in the observation group was significantly higher than that in the control group(x2=5.541,P＜0.05).Before treatment,there was no statistically significant difference in the body mass,BMI,waist circumference,HbA1c,FBG,2hPG,ALT,AST,GGT,CAP,LSM,MDA,GSH-PX,LPO,TNF-α,IL-6,and IL-10 of patients between the 2 groups(P＞0.05);after 24 weeks of treatment,the body mass,BMI,waist circumference,HbA1c,FBG,2hPG,ALT,AST,GGT,CAP,LSM,MDA,LPO,TNF-α,IL-6,and IL-10 were significantly lower than before treatment,while GSH-PX was significantly higher than before treatment(P＜0.05);after 24 weeks of treatment,the body mass,BMI,waist circumference,HbA1c,FBG,2hPG,ALT,AST,GGT,CAP,LSM,MDA,LPO,TNF-α,IL-6,and IL-10 of patients in the observation group were significantly lower than those in the control group,and GSH-PX was significantly higher than that in the control group(P＜0.05).The incidence of adverse reactions in the observation group and the control group during the treatment period was 17.5％(7/40)and 12.5％(5/40),respectively;and the difference in the incidence of adverse reactions between the two groups was not statistically significant(P＞0.05).Conclusion Semaglutide significantly downregulates the levels of FBG,2hPG and HbA1c in patients with T2DM combined with NAFLD and reduces the body mass,waist circumference,liver enzyme level,hepatic fat content,hepatic fibrosis,oxidative stress,and inflammatory indicators.

Objective To explore the therapeutic effects of different doses of radioactive iodine-131 on patients with hyperthyroidism.Methods A total of 574 patients with hyperthyroidism treated in the First Affiliated Hospital of Xinxiang Medical University from April 2020 to April 2023 were sampled for this study and were divided evenly into the observation group and the control group by a random number table,with 287 patients in each group.The control group was treated with high-dose radioactive iodine-131(＞10-15 mCi),while the observation group was provided with low-dose radioactive iodine-131(5-10 mCi).The therapeutic effects were estimated six months after treatment.Data of the two groups of patients before treatment and 3 and 6 months after treatment were compared,including the levels of thyroid hormone(FT4),free triiodothyronine(FT3),and thyroid-stimulating hormone(TSH),which were measured through the fluorescence immunochromatography of serum(obtained by centrifugation of 3 mL fasting venous blood),and the tumor necrosis factor-α(TNF-α),transforming growth factor-β1(TGF-β1),interleukin-6(IL-6),and IL-1,which were measured through the enzyme-linked immunosorbent assay of serum.The salivary gland uptake index and salivary gland secretion index of the patients before treatment and 3 and 6 months after treatment were measured through radionuclide imaging.The incidence of adverse reactions during treatment was documen-ted.The incidence of hypothyroidism in both groups was evaluated 6 months after treatment.Results The total effective rate of the observation group and the control group was 83.27％(234/281)and 92.88％(261/281),respectively,and that of the observation group was significantly higher(x2=12.353,P＜0.05).The FT4,FT3,and TSH levels of the two groups before treatment showed no statistical discrepancy(P＞0.05).According to data collected 3 and 6 months after treatment,FT4 and FT3 levels of both groups significantly decreased,while TSH increased(P＜0.05)compared to corresponding pre-treatment levels;FT4 and FT3 levels of both groups observed 6 months after treatment were significantly lower than those observed 3 months before,in contrast to the growing TSH trend(P＜0.05).At 3 and 6 months after treatment,FT4 and FT3 levels of the observation group were significantly lower than those of the control group,while TSH levels were significantly higher(P＜0.05).The salivary gland uptake index and salivary gland secretion index between the two groups before treatment showed no statistical discrepancy(P＞0.05).At 3 and 6 months after treatment,such indexes of both groups obviously decreased(P＜0.05).However,those observed 6 months after treatment were higher than three months before(P＜0.05).At 3 months after treatment,the salivary gland uptake index and salivary gland secretion index of the observation group were notably higher than the control group(P＜0.05);at 6 months after treatment,no statistical discrepancy was observed between the two groups in terms of the two indexes(P＞0.05).Before treatment,there was no statistical difference in TNF-α,TGF-β1,IL-6,and IL-1 levels between the two groups(P＞0.05).At 3 and 6 months after treatment,the TNF-α,TGF-β1,IL-6,and IL-1 levels of both groups decreased significantly from pre-treatment levels(P＜0.05),and the data observed 6 months after treatment were still lower than those observed 3 months after treatment(P＜0.05).At 3 months after treatment,the TNF-α,TGF-β1,IL-6,and IL-1 levels of the observation group were significantly lower than those of the control group(P＜0.05);at 6 months after treatment,no statistical difference was observed between the two groups(P＞0.05).The incidence of adverse reactions during treatment in the control group and the observation group was 16.38％(47/287)and 8.01％(23/287),respectively,and that of the observation group was significantly lower than the other group(x2=8.457,P＜0.05).At 6 months after treatment,the incidence of hypothyroidism in the control group and the observation group was 12.46％(35/281)and 3.56％(10/281),respectively,and that of the observation group was significantly lower than that in the control group(x2=15.098,P＜0.05).Conclusion Low doses of radioactive iodine-131 work better in the treatment of hyperthyroidism and can effectively alleviate inflammation and salivary gland dysfunction,with less risk of inducing hypothyroidism and adverse reactions.

Objective To develope a clinical decision support system(CDSS)on insulin titration and validate its effectiveness and safety.Methods Eighty patients with type 2 diabetes mellitus treated at the Department of Endocrinology of the First Affiliated Hospital of Xinxiang Medical University from January 2021 to July 2023,who had difficulty in achieving glycemic control on the basis of lifestyle interventions and oral hypoglycemic drug treatments,were selected for the study.The patients were divided into the observation group and the control group using a random number table,with 40 cases in each group.Patients in both groups received oral metformin extended-release tablets,subcutaneous insulin degludec before bedtime,and subcutaneous aspartate insulin injection before three meals for glycemic control.Patients in the observation group were given insulin titration using the CDSS,and patients in the control group were given insulin titration using the conventional method.The retrospective continuous glucose monitoring system was used to monitor time in range(TIR)for glucose,mean amplitude of glycemic excursion(MAGE),mean blood glucose(MBG),standard deviation of blood glucose(SDBG),and the coefficient of variation(CV)of blood glucose.Fasting blood glucose(FBG),2-hour postprandial glucose(2hPG),length of hospitalization,time to achieve standard blood glucose control,and incidence of hypoglycemia of patients were recorded before and after treatment in the two groups.Results There was no significant difference in FBG and 2hPG of patients between the two groups before treat-ment(P＞0.05).The FBG and 2hPG levels of patients in the two groups were significantly lower than those before treatment(P＜0.05).The FBG and 2hPG levels of patients in the observation group were significantly lower than those in the control group after treatment(P＜0.05).TIR of patients in the observation group was significantly higher than that in the control group,while MAGE,MBG,SDBG,and CV were significantly lower than those in the control group after treatment(P＜0.05).The length of hospitalization was 9.0(7.3,10.0)days and 11.0(8.3,12.0)days of patients in the observation group and control group,respectively;and the length of hospitalization of patients in the control group was significantly longer than that in the observation group(Z=-2.408,P＜0.05).The time required to achieve glycemic control was 6.5(5.0,8.8)days and 7.5(6.0,10.0)days of patients in the observation group and control group,respectively;and the time required to achieve glycemic control of patients in the control group was significantly longer than that in the observation group(Z=-2.019,P＜0.05).The incidence of hypoglycemia of patients in the observation group and control group was 20.0％(8/40),12.5％(5/40),respectively;there was no significant difference in the incidence of hypoglycemia between the observation group and the control group(x2=0.827,P＞0.05).Conclusion Compared with the conventional titration of insulin,the application of CDSS can provide decision support during the implementation of a basal-meal insulin regimen,which can lead to more effective glycemic control,improved glucose TIR,reduced glycemic fluctuations,shorter time required for patients to achieve glycemic control,and shorter hospital stays without increasing the risk of hypoglycemia.

Objective To observe the effect of exogenous insulin on the expression of P-glycoprotein (P-gp)and the secretion of insulin in pancreatic beta cells (INS-1 832/13).Methods Insulinoma cells (INS-1 832/13) were cultured with 0.5 μmol/L exogenous insulin for 30 days.MTT assay was used to measure cell viability.Quantitative RT-PCR and western blot were used to detect the expression of P-gp mRNA and protein respectively,and glucose stimulated insulin secretion (GSIS) were measured by radioimmunoassay.Results Compared with control group,0.5 μmol/L exogenous insulin promoted the viability of INS-1 832/13 cells [(102.00±12.99) vs (356.00±35.51),P<0.05] and accelerated P-gp expression [(107.50±17.08) vs (307.50±44.25)] both at mRNA and protein levels [(105.00±12.91) vs (192.50±35.94),P<0.05].Glucose stimulated insulin secretion was positively correlated with P-gp expression level,but had no significant effect on basal insulin secretion.Conclusion Exogenous insulin can promote the secretion function of INS-1 832/13 cells,and the mechanism may be related to the expression of P-gp.
